中文摘要：

为获得大面积射流等离子体,建立了大气压Ar气中1维等离子体射流阵列产生装置。通过电压电流波形、发光图像以及发射光谱等手段诊断了其放电特性,研究了外加电压幅值、气体流速和电源频率等对射流阵列产生的影响,得到了阵列最优工作条件,并获得此条件下阵列的放电功率和传输电荷和活性粒子等参数,进而分析了放电的排斥和耦合机制。发光图像拍摄的结果表明：外加电压幅值为8.5 k V,气体体积流量为20 L/min,电源频率20 k Hz时,射流阵列等离子体喷出管口最长,各管间排斥作用和耦合作用最小,放电最强烈,此时放电功率为101.85 W,传输电荷为1 716 n C。阵列中各管间彼此存在Coulomb力和Lorentz力,出现一定偏移是这2个力综合作用的结果。

英文摘要：

In order to obtain a large area of the plasma jet, we established a one-dimensional atmospheric Ar gas plasma jet array generating device. The characteristics of the discharge were diagnosed using voltage-current waveforms, lumin- ous images and emission spectrum etc., and the influences of the amplitude of applied voltage, the gas flow rate and the frequency of power supply relate on the array＇s plasma generation were studied. The optimum working parameters of the array, as well as the discharge power, the amounts of transmission charge, and active particles at this condition, were ob- tained, and then the repulsion and coupling mechanisms between the discharges were analyzed. According to the luminous images, the optimum conditions of the array can be obtained including the applied voltage of 8.5 kV, frequency of 20 kHz and gas flow rate of 20 L/min, under which the array achieves the longest discharge with the least repulsion and coupling effects between the discharge tubes, as well as the most intensity. Meanwhile, the discharge power and transmis- sion charge are 101.85 W and 1 716 nC, respectively. In the array, there are Coulomb forces and Lorentz forces between the tubes, which induce certain shifts of the plasma jets.
